You know there's something seriously wrong with a programming language when an example program (which is just 20 lines of code) like this is already unsafe.

  Writing a sqlite clone from scratch in C

Last I heard, micro controllers still extensively use C and C-like sibling languages (like The Arduino Language). Most system applications use UI kits like Qt or GTK, which are also C libraries. Most of the Linux kernel consists of C code. Both SQL and NoSQL database backend are written mostly in C, with C++ coming in second, and only a few written in Rust, Zig or Golang (if you're interested in creating your own simple database, this is a great tutorial). TensorFlow and Pytorch, the machine learning libraries used for creating ANN-based architectures, uses libtensorflow and libtorch behind the scene that uses a mix of C and C++ libraries, then there's also GPU stuff like CUDA and RoCM that uses a mix of Fortran, C and Julia. Vulkan is also written in C and is supported in C++. Almost all performant libraries in Ruby, Python, Rust or Julia uses C bindings.

SQL has nothing to do with what's database is written in. SQL is what's used to "talk" to the database, to tell them how to deal with data stored. Databases are written in system programming languages, the most popular being C and C++. Don't believe me? Postgres is one of the top 5 databases. Do yourself a favor, check the repository. Scroll down a little, come back and tell me what language it uses.
